Fractionation of chromatin into urea-soluble chromosomal nonhistone proteins (UP), histones (HP), and DNA-associated nonhistone proteins (NP) revealed that the NP fraction from testicular and prostatic chromatin contains organ-specific acceptors for complexes of 5alpha-dihydrotestosterone (17beta-hydroxy-5alpha-androstan-3-one) and its receptor. This acceptor capacity of androgenic tissue chromatin could be transferred to chromatins from non-target tissues with the NP fraction of DNA-associated proteins. Phosphorylation of chromatin enhanced its hormone-receptor binding capacity.
将染色质分离为尿素可溶性染色体非组蛋白(UP)、组蛋白(HP)和DNA相关非组蛋白(NP),结果显示,睾丸和前列腺染色质的NP组分含有5α-二氢睾酮(17β-羟基-5α-雄甾烷-3-酮)及其受体复合物的器官特异性受体。雄激素组织染色质的这种受体能力可通过DNA相关蛋白的NP组分转移至非靶组织的染色质。染色质的磷酸化增强了其激素-受体结合能力。
